      99% of the time I see usage of Array.prototype.some and Array.prototype.reduce, it would have been much more readable with a manual loop.

      This is the example that prompted the tweet. #1 is way more readable to me, do others agree? All the usage I've seen has been similar in readability to this.pic.twitter.com/OVEfJCHQyI

      Since everyone seems to have a lot of free time to argue with me on the 4th of July. I also heavily dislike the use of unary ! for boolean negation. eg. !true. I've started writing `=== false`.

          @yungsters and I like the explicitness of === false too. It gives you confidence that the variable is a Boolean.

          I’m okay with unary negation if it’s on a value I know to be boolean. But I see it used to negate too many other things (including null or undefined).

          The older I get, the more I dislike unary negation, and its partner in crime, the double-bang idiom for conversion to a boolean. I now lean towards, "Unary negation is only acceptable when applied to something extremely brief, like a single variable or a simple function call."

          To each their own, but personally, I love the !bang. I find it amazingly useful, consise and easy to know what is doing.

          I find it just as confusing as when you say "I'm not not going to do that". The equivalent happens when you use !isIgnored. It just messes with my head and I get confused. Not only that but people use it a lot for boolean coercion, like on empty strings which is pretty gross.

          I also use Boolean() to typecast instead of double bang

          What about `isWhitelisted` function w/o negation, and then `isIgnored = (relative) => !isWhitelisted(relative)`. For me it’s better than both ! before long statement and `=== false` at the end of long statement.
